If you're using chrome, did you make sure to check your browser setting and "enable hardware acceleration"? It's an option somewhere in your settings. Maybe it can help!
I do already have it on and I tried turning it off too to see if it helped yet it didn't affect anything in the game at least up to the error. Ill try to keep you updated as much as I can with comments and with my attempts to get into the game. Thanks for trying to fix this for me and anyone else who may have the issue! have a nice rest of your day and if you send me another reply ill try to reply as soon as I'm free and see it ^^
